A grease hold extends in an axial direction from one end of a rotary pin to an eccentric portion, and a pair of grease injection holes communicating to the grease hole is open on the outer circumferential surface of the eccentric portion. These grease injection holes are arranged so as to be axially separated on both sides from a central portion C of the eccentric portion by L/4 when L is an length of the eccentric portion.

Rotary pin

A sensor installation structure and method for a potentiometer located on the exterior of a fork lift. A sensor cover is fixed to a bracket to protect the potentiometer. The cover has an opening permitting the passage of lead wires. A fluid sealant is charged between the cover and the potentiometer to seal the potentiometer.

Sensor installation structure for vehicles

A steering device for an industrial vehicle such as forklift. A pair of knuckle arms are rotatably supported at the ends of a rear axle. Each knuckle arm supports a rear wheel. A cylinder located in the rear axle includes an actuator rod. A pair of tie-rods couple the ends of the actuator rod to the knuckle arms. A toe angle adjusting mechanism is located between one end of the actuator rod and the corresponding tie-rod. The toe angle adjusting mechanism includes an adjuster pin having an eccentric shaft. The toe angle of the rear wheel that does not have the toe angle adjusting mechanism is adjusted by changing the neutral position of the actuator rod relative to the cylinder. Thereafter, the toe angle of the other rear wheel is adjusted by the toe angle adjusting mechanism, which facilitates adjustment of the toe angle of the wheels. The location and number of angle adjusting mechanisms are varied in alternate embodiments.

Steering device for vehicle

An industrial vehicle has a frame and an axle swingalbly connected with the frame, wherein a cylinder interposed between the frame and the axle selectively extends and retracts so as to absorb a swinging motion of the axle. The cylinder is coupled to the frame and the axle in a rotatable manner within a plane intersecting an axis of a center about which the axle swings.

Structure for supporting cylinders

A device for detecting the wheel angle of forklift rear wheels is disclosed. A cylinder steers the rear wheels by means of steering mechanisms based on manipulation of a steering wheel. The steering mechanisms include kingpins that support the rear wheels to be rotatable in relation to a rear axle. Each kingpin rotates integrally with the corresponding rear wheel. A wheel angle sensor, which includes a potentiometer, is fixed to the rear axle by a bracket. The position of the sensor corresponds to the position of one of the kingpins. The sensor detects the rotational angle of the kingpin as the wheel angle of the rear wheels.

Mounting structure for wheel angle detector and rotation amount detector for vehicle wheel

An installation structure of a rotation detector for detecting a rotation amount of a rotational shaft such as a kingpin. The installation structure prevents wear and damage to an input shaft of the rotation detector caused by a radial force applied to the input shaft and has high detection accuracy by eliminating slack between the rotational shaft and the input shaft. The rotation detector is fixed to a support member rotatably supporting the rotational shaft such that the input shaft is substantially coaxial with the rotational shaft. The input shaft is coupled to the rotational shaft through a rotation transmitting means. The rotation transmitting means permits the axis of the input shaft to be offset from the axis of the rotational shaft and limits relative rotation between the input shaft and the rotational shaft. When the axis of the input shaft is offset from the axis of the rotational shaft, the radial force applied to the input shaft from the rotational shaft is absorbed and mitigated, and the rotation of the rotational shaft is transmitted to the input shaft without loss.

Coupler apparatus for rotation sensor

Rear axle for industrial vehicles

A vehicle having a toe angle adjustment mechanism. The vehicle has a frame member, a steerable wheel, a steering knuckle pivotally connecting the wheel to the frame member about a substantially vertical axis, a steering mechanism for steering the vehicle, and a steering actuator included as part of the steering mechanism for moving in a predetermined direction to cause a steering change. A transfer member is connected to the wheel for transferring a force applied by the actuator to the wheel to effect the steering change. The adjustment mechanism pivotally couples the distal end of the transfer member to distal end of the steering actuator about an adjustable pivot axis. The adjustment mechanism permits adjustment of the toe angle of the wheel and varies the position of the adjustable pivot axis with respect to one of the distal end portions to vary the toe angle.

Toe angle adjustment mechanism for vehicle wheels

A toggle type parking brake lever apparatus capable of surely holding a brake lever at a brake application position is provided. Attached to the brake lever is a pivotable stopper pawl, with which a stopper surface formed on a stopper plate is adapted to be engaged in a brake application condition so as to inhibit the brake lever from being turned in a brake releasing direction. A stopper releasing rod with a push button is provided longitudinally of the brake lever to pivot the stopper pawl, thereby to disengage the stopper pawl from the stopper face. The invention is also applicable to a brake lever which is supported to a lever bracket, tiltably back and forth, and left and right, by means of a universal joint.

Toggle type parking brake lever apparatus

A reservoir tank is disposed in a housing between a front protector and a front panel removably mounted to the front protector, by a support device. The support device supports the reservoir tank in such a way that the position of the tank can be adjusted. When the front panel is removed and the reservoir tank is moved towards the front of the forklift, the operation of adding brake fluid can be carried out with ease as there are no obstacles above the reservoir tank.
